cpu_rate

cpu_rate is a program written by Robert G. Brown intended to
encapsulate a number of simple microbenchmarks of systems performance.
It uses its own timing harness, which in turn uses the CPUs onboard
cycle counter for direct timing where this is available. For example,
it encapsulates a variant of the well known stream benchmark, as well
as the venerable savage (trancendental) benchmark. This program is in
the process of being rewritten yet again so that it will eventually be
"easy" to add new code fragments to microbenchmark.
